UNION FOR UNANALOGOUS MATERIAL.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application led December 7', 1915. Serial No. 65,612.

T0 all whom t may concern:

Be it known that I, ALBERT F. a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Unions for Unanalogous Material, of which the following is a specification, the principle of the invention being herein explained and the best Inode in which I have contemplated applying that principle so as to distinguish it from other inventions.

This invention pertains in the broad sense to a union purposed as set out by the title.

More particularly the idea will ordinarily be employed in effecting a precise connection between a pair of members which could not be readily and feasibly accomplished without entailing undue expense. The drawings exemplify a union between a metal stamping and a molded glass dome.

The object of my invention is the provision of a firm connection and incidentally of a hermetical seal which could be quickly and economically effected, which is of sufcient strength for ordinary purposesV and which makes allowance Vfor variations in size of the portions or edges which are to be joined.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown preferred and modified embodiments of the invention, but it is to be understood that many other changes, variations and modifications can'be resorted to which come within the scope of the claims hereunto appended.

Adverting to the drawings: Figure lis a part elevation and part section of a structure embodying my invention. Fig. 2 is a section on line A-A of Fig. 1. Fig. 3 is an enlarged section on line B-fB of Fig. 1. Fig. 4 is a section on line C-C of Fig. 3. Fig. 5 is a broken interior elevation on line D-D of Fig. 3. Fig. 6 is a View corresponding to Fig. 3'showing a modified application of my invention. Fig. 7 is a similar view of a further modification. Fig. 8 is a full sectional view showing the manner of utilizing the principle of my invention in a reversed manner.

I happen to employ the principle of this invention in the manufacture of a vending SGHROEDER,

machine employing a molded glass cover orV dome in order to permit. the contents thereof to be seen by the purchaser. In practice it becomes necessary to feasibly connect such a member composed of friable material with metal parts. It is well known that metal may be shaped so that corresponding parts will all be of uniform size, but this is not possible in the case of molded glass such as the domes in commercial use. For this reason it occurred to me to contrive a mode of ing in its side an opening adapted to be closed by a door 2 hinged in any approved manner at 3 and capable of having its free end secured by means 'of a padlock 4. The purpose of this door will be hereinafter explained. The upper part 5 of the container 1 is formed so as to project first inwardly and vthen upwardly whereby to form an annular seat 6 and an annular flange 7 as is clearlyseen in Figs. 1 and 3. The flange 7 is provided with a plurality of, and in this instance with four, slots 8 of angular shape. These slots are clearly shown in Figs. l and 5. Secured to the under side of the. seat 6 at a point opposite one of the entrances Vof the slots'S is a spring finger 9 which extends inwardly and is then arched upwardly to bear against the inner side of the flange 7 at such slots and as may be seen in Fig. 3. The extremity 10 of the finger 9 is bent slightly away from the flange 7 in order'that it may exercisethe function of a catch-in a manner soon to be manifest.

Another metal member is intended to have a detachable connection with the upper edge of the container 1. I have elected to adopt for such Vconnection the well known bayonet-joint in cooperation with the anguupper edge 12 is turned inwardly. `PassedA through four equi-spaced pairs of alined openings are four pins 13. It will be seen in Fig. 2 that these pins are inserted in such its confines.

a manner that the heads 13 are on the outside and the opposite extremities 15 project a certain distance beyond on the other or inner side of the channel members 11. An intermediary portion of the pins 13 may be roughened or provided with burs as shown. n effecting connection between the container 1 and the member 11 after the manner of a bayonet joint, the member 11 is turned until the extremity 15 is above the entrances to the slots 8 which they are then caused to enter. During such insertion the extremity 15 of one of the pins engages the sloping surface of the free end 10 of the spring finger forcing it inwardly as indicated by dotted lines in Fig. 3. Thereafter a slight rotation carries the pins to the innermost ends of the slots 8 and this permits the spring finger 10 to snap back against the flange 7 and thereby act as a catch to prevent a rotation in the reverse direction.l Preparatory to again separating the member 11 from the container it becomes necessary to first flex the extremity 10 inwardly by manipulation from the interior. The molded glass dome 16 having the usual irregularly shaped annular edge 17 is next gravitationally brought to rest upon the four pins 13 leaving some free space to either side thereof as is clearly illustrated in Figs. 1 and 3. Finally I pour plaster of Paris in fluid form into the member 11 so as to completely iill the same and set against all surfaces within After the plaster of Paris has become hardened to make a hermetically sealed unit of the parts its top surface may be shaped or finished off in any desired manner and painted or water-proof coated a color t match the adjacent metal parts, thereby concealing its identity. It should be noted particularly that the edge 17 is completely covered and that the indurated material is furthermore protected and held in place by reason of the inwardly turned edge 12. Tt will now be manifest that the removal of the dome 16 together with the member 11 will only be possible to a person having access through the door 2 for the purpose of releasing the catch 10.

The modification seen in Fig. 6 resides in two simplifications in that the upper outer edge 19 of the member 11 is not turned inwardly and in that the pins 20 are plain or wherein the indurate material 24C is increased or 'strengthened by sloping the same upwardly a given distance above the upper edges of the member 11.

The final modification illustrated in Fig. S represents the manner in which my invention may be utilized in reverse position. A jar 25, vsay of Crockery having an irregular upper edge 26 and lower down a pair of handles 27 is given a hermetically sealed and locked fit with a hollow metal member 28 having one Vinwardly turned edge 29, by employing in similarV wise some material 30 having indurating properties.

I claim: j

1. A union for unanalogous material comprising a pair of metal members having a detachable connection with each other, one of said members being hollow and provided with an entry, the other of said members being fashioned with a groove in the shape of a loop, and a glass compartment having a single opening in communication with said hollow member, the edge about said opening conforming to and loosely inserted in said groove, and indurating material for hermetically sealing the edge of said glass in said groove.

2. A union for unanalogous material comprising a metal compartment having a circular opening and provided'with a door, a ring having a bayonet connection with said compartment around said opening, said ring being fashioned with an annular groove, a molded glass dome having its circular edge disposed in said groove, indurated material enveloping said 'edge and occupying said groove, and an automatically operating catch for locking said bayonet connection interiorly.

Signed by me, this 29th day of Nov.,1915. ALBERT F. SCHROEDER.
